Femoral Artery.—In the Chimpanzee it begins about the level of the middle of Poupart's ligament and runs distally for l£ in. It gives off the arteria profunda femoris at that point and is continued as the superficial femoral artery. It passes between the two parts of the adductor magnus and becomes the popliteal artery. There is no Hunter's canal. The following are the branches in Man and the Chimpanzee :—
